Draft Plan Bay Area 2050+

After more than two years of public discussion, technical analysis and refinement, the Metropolitan Transportation Commission (MTC) and the Association of Bay Area Governments (ABAG) have released Draft Plan Bay Area 2050+ for review and comment. The plan contains 35 strategies representing public policies and investments that can be implemented in the Bay Area by 2050 to help the region build more homes, reduce commute times and create vibrant downtowns and natural areas for everyone to enjoy. The plan’s strategies also aim to keep people safe from natural hazards, support a strong economy and provide stable housing for those who need it most.  

Unique to this plan cycle is the parallel Transit 2050+ planning effort, which culminated in the first-of-its-kind plan to re-envision the future of Bay Area public transit, in partnership with transit operators across the region.  

Public comments on the draft plan, along with the Draft EIR, the Draft Implementation Plan and accompanying supplemental reports, are due by 5 p.m. on Thursday, December 18, 2025.  See below for opportunities to participate and provide comment.
